DiffSinger
DiffSinger is an open source singing voice synthesis and text-to-speech framework using shallow diffusion.
DiffSinger is an open source PyTorch implementation for singing voice synthesis and text-to-speech models. It uses a shallow diffusion mechanism and supports models like DiffSpeech and NeuralSVB. The system accepts inputs such as lyrics, MIDI, and text, and generates mel-spectrograms and audio waveforms using vocoders like HiFiGAN and NSF-HiFiGAN. It is designed for researchers and developers working on generative voice models. The repository includes documentation, inference scripts, and dataset support for PopCS, OpenCpop, and Ljspeech.
